' 2 Claims. (cram-5) The present invention relates to balance body II.

I claim:

1. A balance weight attachable to a tire retaining flange of a vehicle wheel assembly comprising a heavy body portion and a pair of longitudinally spaced overhanging lip portions, said lips and body portion being sufiiciently spaced to receive therebetween an edge portion of said flange, adjustable clamping means for clamping said lips against one side of said flange, said means engaging said flange between said lip and on the opposite side thereof.

2. A balance weight attachable to a tire retaining flange of a vehicle wheel assembly comprising a heavy body portion and a pair of longitudinally spaced overhanging lip portions, said lips and body portion being sufliciently spaced to receive therebetween an edge portion of said flange, adjustable clamping means for clamping said lips against one side of said flange, said means engaging said flange on the opposite side thereof;
